Mechanical Design Engineer Thermal Systems, FEA & CFD

We're looking for a Mechanical Design Engineer with hands-on experience in SolidWorks + FEA/CFD + Heat & Mass Transfer + manufacturing/fabrication.

Location: Bengaluru / Attibele, Karnataka

Experience: 3–6 years

Work Mode: Full-time | On-site

EarthEn Energy is building next-generation thermal energy storage solutions to decarbonize industrial heat. Our thermal energy storage systems enable industries to store and deliver high-temperature heat reliably using renewable energy and waste heat.

We are looking for a Mechanical Design Engineer with strong thermal engineering and simulation experience to work on the design and development of thermal energy systems, heat-transfer equipment and industrial mechanical products.

• Take mechanical products and thermal systems from concept → 3D CAD → engineering calculations → detailed drawings → prototype → manufacturing → testing → design improvement.
• Design and develop heat exchangers, thermal systems, pressure-containing components, ducting, manifolds, piping, frames, supports and industrial equipment.
• Develop detailed 3D models and assemblies using SolidWorks.
• Prepare manufacturing-ready GA, fabrication, part and assembly drawings.
• Apply GD&T, tolerance stack-up, DFMA and manufacturability principles.
• Perform heat-transfer, thermal, mechanical and structural calculations.
• Work on FEA and CFD simulations, including thermal/structural/flow analysis.
• Select suitable materials for mechanical and high-temperature applications.
• Design components involving sheet metal, welding and fabrication.
• Work with manufacturing teams, vendors and fabricators to take designs from CAD to physical products.
• Support prototype development, testing, validation and design iterations.
• Prepare and maintain BOMs, engineering documentation and revision-controlled drawings.

• Strong SolidWorks proficiency
• 3D part and assembly modelling
• Engineering & manufacturing drawings
• GD&T and tolerance stack-up
• Welding and fabrication design
• Sheet-metal design
• FEA and CFD / SIMULIA
• Heat and mass transfer
• Basic thermal, mechanical and structural calculations
• DFMA
• BOM preparation
• Material selection

• Pressure vessel codes and standards
• Piping standards
• Flange selection and design

• HVAC and process ducting design
• Damper / valve selection
• Heat exchanger design
• Thermal energy storage systems
• Industrial heat-recovery systems
• High-temperature equipment
• Experience working with fabrication/manufacturing vendors

• B.E./B.Tech in Mechanical Engineering
• M.E./M.Tech in Thermal Engineering or a related field is an advantage.

We are looking for someone who is not only a CAD designer but can connect mechanical design, thermal engineering, simulation and real-world manufacturing.

You should be comfortable taking ownership from design and calculations through fabrication, testing and iteration.
